WASHINGTON, Sept. 8, 2014 /PRNewswire-USNewswire/ -- Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Researchers have clear visual evidence of Europa's icy crust expanding. However, they could not find areas where the old crust was destroyed to make room for the new. While examining Europa...

NASA/JPL Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth. Researchers have clear visual evidence of Europa's icy crust expanding. However, they could not find areas where the old crust was destroyed to make room for the new. While examining Europa images taken by NASA's Galileo orbiter in the early 2000s, planetary geologists Simon Kattenhorn, of the...

Voyager 2 Triton Map
2014-08-24 04:35:17

redOrbit Staff & Wire Reports - Your Universe Online In honor of the 25th anniversary of Voyager 2’s first up-close look at Neptune and Triton, NASA has “restored” footage obtained by the probe and used it to construct the highest-quality global color map of the moon to date. According to the US space agency, the map was produced by Dr. Paul Schenk, a scientist at the Houston-based Lunar and Planetary Institute (http://www.lpi.usra.edu/) (LPI), and has also been used to...

renewed cloud activity on titan
2014-08-13 07:12:17

Preston Dyches, NASA Jet Propulsion Laboratory NASA's Cassini spacecraft recently captured images of clouds moving across the northern hydrocarbon seas of Saturn's moon Titan. This renewed weather activity, considered overdue by researchers, could finally signal the onset of summer storms that atmospheric models have long predicted. A movie showing the clouds' movement is available at: http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA18420 The Cassini spacecraft obtained the new...

Cassini spacecraft
2014-08-08 08:19:25

Preston Dyches, NASA Jet Propulsion Laboratory NASA's Cassini spacecraft will execute the largest planned maneuver of the spacecraft's remaining mission on Saturday, Aug. 9. The maneuver will target Cassini toward an Aug. 21 encounter with Saturn's largest moon, Titan. The main engine firing will last about a minute and will provide a change in velocity of 41 feet per second (12.5 meters per second). This is the largest maneuver by Cassini in five years. No other remaining maneuver...

volcanic eruptions on Io
2014-08-05 04:32:03

April Flowers for redOrbit.com - Your Universe Online In August of last year, Jupiter's moon Io surprised astronomers with three massive volcanic eruptions within a two-week period. Two studies, accepted for publication in the journal Icarus, suggest that these volcanic "outbursts" might occur more commonly than previously thought. "We typically expect one huge outburst every one or two years, and they're usually not this bright," said Imke de Pater, professor and chair of astronomy at...

moon is lemon shaped

redOrbit Staff & Wire Reports - Your Universe Online More than four decades after US astronauts first visited the lunar surface, scientists have finally determined both the actual shape of the moon and the forces responsible for giving it that form, according to a new study published this week in the journal Nature. As it turns out, the moon is somewhat flattened with a bulge on one side, the authors told Douglas Quenqua of the New York Times. University of California, Santa Cruz...

Enceladus South Pole
2014-07-29 03:45:31

Preston Dyches/Dwayne Brown/Steve Mullins, NASA Scientists using mission data from NASA's Cassini spacecraft have identified 101 distinct geysers erupting on Saturn's icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon's underground sea all the way to its surface. These findings, and clues to what powers the geyser eruptions, are presented in two articles published in the current online edition of the Astronomical Journal. Over a period...

NASA Seeks Proposals For Science Instruments For Future Mission To Europa
2014-07-16 03:18:13

Dwayne Brown, NASA NASA has issued an Announcement of Opportunity (AO) for proposals about science instruments that could be carried aboard a future mission to Jupiter’s moon Europa. Selected instruments could address fundamental questions about the icy moon and the search for life beyond Earth. “The possibility of life on Europa is a motivating force for scientists and engineers around the world,” said John Grunsfeld, associate administrator for NASA’s Science Mission...

Planet Pluto -- Pluto is the ninth and smallest planet of our solar system. It was discovered by the astronomer Clyde Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 (although the body was first photographed on March 19, 1915). Tombaugh was searching for a "Planet X" to explain the orbit of Neptune; further analysis, with seven decades more data about Neptune's position, has resolved the perceived anomaly without need for an additional gravitational pull on Neptune....

Uranus -- Uranus is the seventh planet from the sun. It is a gas giant. Physical characteristics Uranus is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium (in contrast to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) are in many ways similar to the cores of Jupiter and Saturn minus the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather...
